Just for reference: I asked at the linux-acpi list and they advised me
to add termal.crt=<value> to the kernel boot paramters, which I did
(<value>™) and it actually sets the temperature of the virtual device.

Now I get:

# acpi -V
Thermal 0: ok, 64.0 degrees C
Thermal 0: trip point 0 switches to mode critical at temperature 99.0
degrees C
Thermal 0: trip point 1 switches to mode passive at temperature 105.0
degrees C

and

acpitz-virtual-0
Adapter: Virtual device
temp1:
  temp1_input: 66.000
  temp1_crit: 99.000

coretemp-isa-0000
Adapter: ISA adapter
Physical id 0:
  temp1_input: 66.000
  temp1_max: 86.000
  temp1_crit: 100.000
  temp1_crit_alarm: 0.000
Core 0:
  temp2_input: 63.000
  temp2_max: 86.000
  temp2_crit: 100.000
  temp2_crit_alarm: 0.000
Core 1:
  temp3_input: 66.000
  temp3_max: 86.000
  temp3_crit: 100.000
  temp3_crit_alarm: 0.000

pkg-temp-0-virtual-0
Adapter: Virtual device
temp1:
  temp1_input: 67.000


Thanks for your hints,

Thomas
